Question
Why did all of my scheduled workflows fail? What does the error “Logon Failure: unknown user name or bad password” mean?
Answer
This error is due to the credentials that are used for the scheduler are no longer valid and have most likely expired. To fix this, the Run As setting has to be updated in the scheduler machine. Someone with local admin rights to the machine should go to the System Settings (Alteryx > Options > Advanced Options > System Settings) then click Next until the “Run the Worker as a Different User” menu is selected and update those credentials.
